"Never be optimistic about anything that's going on in the Middle East," said Arthur Abramson, the executive director of the Baltimore Jewish Council. "It's a massive concern because Iran presents an existential threat to Israel."

He said he thinks the deal doesn't go far enough and wants to see a complete dismantling of Iran's nuclear program. To him, the deal, which stands until a broader agreement is reached in six months, could be troublesome if Iran stalls and doesn't stick to its word.

"Six months -- I think anything beyond these six months could create nothing but further problems," Abramson said.

Given the fact that Iran's regime has constantly threatened Israel, Abramson said many in the local Jewish community are skeptical about the regime's current intentions.

"I think it's a huge step forward," argued political analyst Doni Glover, who said Iran has reason to follow through.

The country's economy is in shambles and has been in recession for years because of international sanctions. Some of those sanctions will now ease but can be imposed again.

"A chokehold is being put on them economically. I would think it has major ramifications on their economy, on their ability to grow their infrastructure," Glover said.

But Abramson said the U.S.'s ability to verify Iran is actually scaling back its program will be important.

"You can create all these images to make it look like you're doing something, and the Iranians are good at it, but unless you can verify whatever they supposedly have done, I'm not sure how good you can base the success of this," he said.

Even though there are skeptics, Secretary of State John Kerry is vowing no one will be deceived by Iran moving forward and insists the deal that was struck has made the world safer.
